DERIVING MOVEMENT BEHAVIOUR FROM SENSOR DATA

摘要

Method for estimating movement behaviour of a user of a mobile communication device by a neural network comprising one or more lower and one or more higher hidden layers. The method comprising a step of obtaining (401) sensor data from sensors in the mobile device; a step of obtaining (402) measurements related to a movement of the user; a step of labelling (403) these measurements as weakly labelled data; pre-training (404) the lower hidden layers to estimate the measurements from the first set of sensor data; a step of obtaining (405) a second set of sensor data wherein movement behaviour of the user is labelled as labelled data; a step of training (406) the higher hidden layers with the labelled data to estimate the movement behaviour of the user as said output.
